Perimeter parking lot landscape provides for the enhancement and screening of parking lots by requiring a scheme of landscape along public streets. A perimeter landscape yard is required for all parking lots and the landscape treatment shall run the full length of the parking lot where it abuts a public right-of-way, excluding an alley. In the case of parking located at the front of the building, the front landscape yard requirements control. The perimeter parking lot landscape yard shall be improved as follows: (Figure 23-2: Parking Lot Perimeter Landscape Yard)

1.  The perimeter landscape yard shall be a minimum of five (5) feet in width.
